Data loss / corruption / duplications when operating on large tables

Has anyone encountered this problem in the current versions of Obsidian?

I have experienced content duplication in tables before, so I avoid using tables in Obsidian at all costs, but now I need to create a medium table (~200 rows), and I don’t know whether to take the risk or just use Excel instead.

(If anyone encounters this again, Notepad++ has a handy feature for automatically removing duplicate lines.)
